Over the next year, new research will provide Western Australian growers with information to compare the cost effectiveness of purchasing different information layers for variable rate technology (VRT) zone application maps... In addition to a comprehensive literature review, knowledge and experiences from growers, agronomists and precision agriculture practitioners about the benefits and drawbacks of each information layer will be incorporated into the study... "With seeding well underway in the west, decision making about the cost effectiveness of purchasing different map layers for variable rate technology (VRT) zone application will be top of mind for many growers," Mr White said...

The extent of beet western yellows virus (BWYV), which has decimated canola crops in parts of South Australia, Victoria and New South Wales, has been mapped after extensive testing of samples provided by growers... A high incidence of BWYV associated with severe crop damage was confirmed earlier this season in canola crops in parts of SA and Victoria and unusually high infections were also found in several canola paddocks in NSW... Check for the build-up of numbers and any significant numbers of winged aphids in a population, which signals that flights may be about to occur," says Dr Umina, who is leading GRDC-funded research into insecticide resistance in GPA...

Trials measure mapping profitability.. Frank D'Emden (left) and Dowerin grower Andrew Todd are assisting the GRDC RCSN with trials investigating various mapping layers for variable-rate technology... The trial is looking at the use of PA tools with mapping layers, such as electromagnetic induction (commonly EM38), gamma radiometrics and normalised difference vegetation indices (NDVIs), to develop more 'high-tech' VRT zone application maps...

Rural Management Strategies consultant Chris Minehan says using Yield Prophet and plant available water capacity mapping to manage nitrogen can be more profitable than applying a blanket rate... Recent research conducted by Rural Management Strategies in New South Wales has found that managing nitrogen separately across varying soil types using Yield Prophet and plant available water capacity (PAWC) mapping can be more profitable than applying a blanket rate of nitrogen due to savings in fertiliser costs... During the 2013 and 2014 winter cropping seasons, the Grains Research and Development Corporation (GRDC) funded trials at Barmedman to demonstrate the use of Yield Prophet and PAWC mapping to improve nitrogen decision-making in wheat and canola...

" Date: 18.01.2016 pH maps cut the cost of tackling soil acidity.. Victorian grower Evan Lewis expects to reduce his expenditure on lime by almost 70 per cent this year through the use of variable-rate technology... Compared with a blanket lime rate of 2.5 tonnes per hectare applied across the Lewis family's property for 13 years, pH mapping will enable Evan to tackle the acidic and sodic imbalance in his soils with lime rates ranging from just 1.2 to 2.1t/ha in 2016...
